Poor skylight installation by builders often leads to leaks, water damage, and expensive repairs. Many cut corners, skip important steps, or use low-quality materials. These choices save money in the short term but cost homeowners more in the long run.

In this skylight replacement project in Toronto, The Roof Whisperer fixed issues caused by poor workmanship. We began by removing the old skylight and preparing the curb. To improve drainage, we sloped the curb with 2×4-inch boards. This step helps water run off instead of pooling around the skylight. We then added trim boards and painted the inside of the curb for a clean finish.

Next, we focused on waterproofing. Our team installed a two-ply SBS membrane system with both base and cap layers. This high-quality material creates a strong, watertight barrier and boosts the roof’s resistance to harsh weather.

The final step was installing a Velux FCM 3434 Clean Energy Plus skylight. This model is known for strength, energy savings, and long-lasting performance. We secured it tightly to the curb and sealed it into the SBS system. With this method, the homeowner can enjoy natural light without worrying about leaks.

The results speak for themselves: a leak-free skylight, improved energy efficiency, and a refreshed look that adds value to the home.
